The prohibitive cost and size of traditional television tuners are preventing the spread of television to poorer areas and mobile applications. Fully integrated television tuners could reduce the size and cost but currently face issues with noise and linearity which are both strongly dependant on the corresponding specifications of the lownoise amplifier (LNA). Noise and linearity face a trade-...

A new low power 33 GHz low noise amplifier (LNA) is proposed in a 0.18μm CMOS technology.
